I screwed up my xbox.

Hey, I'm new with mod chips, I just put mine on and my xbox is already broken. It was working fine for about 2 days. I started messing with the settings and now the picture is in black and white, I have no sound, and the picture keeps jumping off the screen... sorta like a broken tv. I think I changed pal pr ntsc to something else. Please help I don't know what to do. Maybe is there is a manual restart or something that will totally start my system over. Please help.

Sounds like you changed your Xbox from NTSC (US signaling standard) to PAL (Europe and just about everywhere else signialing). You can either FTP to your box and replace the evox.ini (then reboot). Or just find the setting to change it back if you can see the menu well enough.
